The catch
Marantz CINEMA 40
Nine built-in main amplifiers is still all the larger model has. Two external amplifier channels are needed for 7.1.4.
Side by side
Marantz CINEMA 40 vs CINEMA 50: CINEMA 40 gets old-video routing and a seventh input
Quick verdict
Supported analog-video sources or a seventh HDMI input that solve an actual connection problem make CINEMA 40 the choice. CINEMA 40 can send supported analog video through HDMI, while the original CINEMA 50 has no analog-video input route. CINEMA 50 already covers nine powered main channels, eleven-channel processing with an external amp and four independent sub outputs. The 40 does not remove the external amp needed for 7.1.4.
Before you buy
Why, and what it costs you
Holding on to an old console can change the receiver you need more than adding two speakers would
Your family may use modern HDMI players every day and an older composite or component device now and then. When the projector already has one HDMI cable installed, CINEMA 40 can convert supported analog video onto that route. CINEMA 50 has no analog-video input, so it needs a separate verified conversion path. Check the exact source format before picking the 40 for this reason. An RCA connector or an upscaling label doesn’t establish compatibility with every vintage signal.
Where this comes from
The full connector inventory and supported conversion, matched against sources from different generations and a display cable already installed. No improvement in picture quality is claimed.
The catch
Marantz CINEMA 50
With no analog-video input route and six HDMI inputs, you may need extra source-routing hardware.

- Why pick it
- A supported composite or component source has to reach the HDMI screen cable you already have.
- Direct permanent inputs are needed for seven HDMI sources.

Marantz CINEMA 50
- Why pick it
- The system is covered by six HDMI sources, and analog-video conversion is not needed.
- The current offer makes sense for the same expansion plan, nine amps with eleven channels.

What this page compares
Marantz CINEMA 40 vs original CINEMA 50 for older consoles, a crowded source cabinet and 7.1.4, including what the upgrade changes and what still needs an amp.
These neighboring nine-amplifier Marantz models top out at the same main-speaker expansion. Source routing can justify the step up. Do not assume an improvement in sound.

Differences you will notice

How we worked this out
The full connector inventory and supported conversion, matched against sources from different generations and a display cable already installed. No improvement in picture quality is claimed.
A seventh input earns its place when it keeps a permanent setup intact
Six HDMI inputs get filled by two consoles, a PC, a disc player, a streaming box and a television box. A seventh compatible player then forces a cable swap, another display route or an external switch on CINEMA 50. CINEMA 40 has a seventh rear input. That is a concrete convenience for a collection like this, but a household with three sources gains nothing from the spare. All seven are still at the rear, so the upgrade doesn’t give visitors an easy front connection.
How we worked this out
Six named permanent source roles plus a seventh device, set against six rear inputs and seven. The example is a scenario about source count and doesn’t claim anything about what a typical household owns.
The model upgrade leaves the amplifier shortage in place
It takes eleven main amplifier channels to run seven ear-level speakers and four heights, and each receiver has nine. Replacing CINEMA 50 to get away from a separate stereo power amp won’t work with CINEMA 40. Both handle eleven-channel playback through appropriate external amplification, and both already have four independent sub outputs. Pick the 40 for a connection it really adds, or look at an eleven-amplifier receiver if one-box 7.1.4 is what you want.
How we worked this out
7 plus 4 equals 11, and both have nine built-in amplifiers. Because sub and processing capabilities are shared, no unsupported benefit is credited to the flagship.

Spec by spec
Where they really differ
| Spec | Marantz CINEMA 40 | Marantz CINEMA 50 | In practice |
|---|---|---|---|
| Supported older video | Composite/component conversion to HDMI | No analog-video input route | CINEMA 40 lets qualifying legacy sources share one HDMI display run. |
| Permanent HDMI sources | Seven rear inputs | Six rear inputs | No separate input switch is needed to keep the seventh device connected. |
| 7.1.4 power | External stereo amp required | External stereo amp required | Moving up a model doesn’t fix an amplifier shortage for eleven speakers. |
| Powered subs | Four independent outputs | Four independent outputs | The number of subs by itself doesn’t justify the upgrade. |
Trade-offs
What each pick costs you
With Marantz CINEMA 40
- Look at the exact format of the old source. Analog conversion isn’t guaranteed for every vintage console signal.
With Marantz CINEMA 50
- Audyssey XT32 is included on both. Optional Dirac licensing and any external power amp you need come on top.
Change of plan
When the answer changes
A route is needed for an analog-video source or a seventh HDMI player
Go with Marantz CINEMA 40. Those connections come with CINEMA 40.
Decision guide
Before you buy
One receiver should keep old and new players usable, without you paying for an upgrade that leaves the speaker problem as it was.
What this page can’t tell you
- We invent no measured sound-quality reason to favor either model. When the extra connections would go unused, the current offer decides it.
